No 3G service after winterboard Update

Hi.
I just update winterboard through Cydia on two iphones, one 3G and one 3GS. Cydia sæson updated a couple of other things (some library Stuff i think), and when the Update was completed, there was NO 3G service on either of the iphones.. I Can Call and SMS and connect to wifi, but when i try to Uwe the Internet without wifi (but using 3G) it says i don't have any service.. Tried uninstallibg winterboard, but still no service!
